You can also browse a pretty good selection of 100% bloatware free PC's at Microsoft's Signature Edition store:

Yep, I was going to suggest this as well. Also, as others have stated buying a PC with an SSD is definitely recommended. I bought a lower end Dell and while it is ok for what it is, I notice a big difference from my work PCs that have SSDs.
I also find that browsers are definitely pulling more resources than in the past. Whether that is a function of the sites, or the browsers, I'm not sure.
I'd definitely recommend a bloatware free machine from the Microsoft store or other source, or reloading the OS yourself, and getting a machine with a good amount of RAM and an SSD.
